deop urself and try again... not saying it'll work but I'm trying to figure out a solution for this error.

You need to make sure you have Java 7 installed and not 6... CentOS will not detect that it needs to update from 6 to 7, you will actually need to uninstall 6 and install 7. If you don't want to do this simply remove the NetherOres mod from your mod folder.

Temporarily remove all your plugins and see if you have the issue still. If it works slowly re-add the plugins 1 by 1 and see which one causes the error.

How about you stop talking in all caps, create your own post with the posting guidelines?

Go into your add/remove programs. Uninstall any java 6's and make sure only Java 7 is installed.... install java 7u5

Make sure you don't /reload This will break crafting any modded items. You need to /save-all and /stop and restart the server.

What is your minecraft name you are trying to login under?

This happens when your client expects an item to be one number... and the server is giving another number... Make sure your crowbar item ID is set to the right one...

Update your java to 7u5

This is the second time I've seen this error. I had the other guy remove NEI from the mod folder and he said it didn't work. Try that and let me know. Are you OP or anything?

Nerd rage, yo.

Repopulate means.... once your deleted your .technicpack folder re-run teh techniclauncher.exe and have it automatically download tekkit for you.

What plugins are you using?

Are you using java 64bit or 32 bit? You need to replace your "java" with the file path to your java.exe in your program files/java folders.

10 seconds to fill up 1.5 gigs of ram.... only plausible if the chunk is overloaded...

In your technic launcher... go to options... and the allocated ram move it to 512 and hit ok... if problem still happens... change it to the 15xx one..

Delete your .technicpack folder and let it repopulate... update graphics card... and update your java from u4 to u5

It failed to handle a packet which is why it kicks everyone off... essentially your server is having issues handling the packet it receives when you attempt to do this action... try this on a blank world and see if its the same issue.

There is a lot of bugs with the jungle growth.... I'd suggest waiting for 1.3

If this is running off the same computer as you are playing on... the ip you should try to connect to is... localhost

Update to java 7_u5 from u4... Update your graphics card... Delete your .technicpack folder and let it repopulate.

Kirbyatebob, if you are still having this issue I would be more than happy to help you. Since incompetent posters like to post their problems in other threads please email me: [email protected]

Make sure your graphics card is up to date. Do you have optifine? Also try hitting the F7 key in game.

Update your graphics card driver.

Remove your NEI from the mods folder and try again, if this fixes it, it is something wrong with your NEI.
